3. distribution of Galeopsis ladanum in Germany based on an analysis of herbarium material is smaller than that indicated in plant atlases

Creator:

article and TEXT
Subject:
chorology, distribution atlases, Galepsis, Germany, herbaria, and land use
Language:
English
Description:
The distribution of Galeopsis ladanum in Germany and adjacent regions was determined by a revision of specimens of Galeopsis subgen. Ladanum in major Central European herbaria. This distribution was compared with that indicated in plant atlases. For the west of Germany, beyond the range of G. ladanum, plant atlases are often misleading as they indicate the presence of this species throughout two German states and Luxembourg, but no herbarium records could be found for these regions. In other federal states, herbarium material indicated a historical distribution that is not reflected in plant atlases. Some Red Data Books give wrong assessments of the degree of endangerment. Exaggerated ranges are mapped if (i) guide books are misleading, (ii) recorders are unfamiliar with the species and (iii) similar species exist.

Language:

Description:
This is the first complete inventory of alien vascular plant taxa for the Slovak Republic. The presented database contains information on family affiliation, residence status, invasion status, time of introduction, mode of introduction, planting purpose, abundance and distribution within phytogeographic regions, types of invaded habitats and syntaxa, and life forms and geographical origin of the alien taxa. In total, 21.5% of the total flora is made of up of alien taxa, comprised of 282 archaeophytes that make up 6.6% and 634 neophytes 14.9% of the total number of taxa, respectively. The majority of the alien taxa are casuals (57.6%), 39.1% are naturalized and 3.3% invasive. Most of them come from Europe (32.8%) and Asia (32.8%), followed by Africa (12.2%) and North America (10.8%). The database contains members of 98 families of which the Asteraceae, Brassicaceae, Fabaceae, Poaceae, Amaranthaceae and Rosaceae are the most represented. Almost 50% of the alien taxa are therophytes. Hemicryptophytes (26.3%) and phanerophytes (15.6%) are also abundant. More of the alien taxa were introduced deliberately (49.0%) than unintentionally (43.9%), and the majority were introduced as ornamental plants (55.9%). Of the total number of alien taxa, 45.2% are recorded from less than five localities. Most of them prefer human-made habitats; they are found in 137 phytosociological alliances, with those richest in alien taxa categorized as synanthropic vegetation.

5. Invertebrates in urban areas: a review

Language:

Description:
As urbanisation is set to continue, understanding the impact on wildlife becomes increasingly important if we are to be able to conserve biodiversity. As an excellent group of bioindicators, invertebrates can allow us to understand some of the forces in urban areas which impact upon biodiversity and wildlife populations. This paper discusses some of the trends in the abundance, diversity and richness of invertebrates related to urbanisation and the specific urban environmental and traffic factors which may be at play., Elizabeth L.

7. Long term changes in abundance of Coccinella septempunctata (Coleoptera: Coccinellidae) in the Czech Republic

Language:
English
Description:
Since 1978, the abundance of Coccinella septempunctata L. has been recorded at a hibernation site in the western Czech Republic. Over the years, abundance varied by two orders of magnitude and a long-term trend for decrease in C. septempunctata abundance was observed beginning in the early 1990s. This recession was correlated with the decreasing abundance of its dominant prey, cereal aphids. The acreage of small grain cereals and other crops suitable for breeding C. septempunctata populations also decreased. The change in abundance of cereal aphids may be associated with a dramatic decrease in fertilizer input after 1990. Decreasing fertilizer use has changed the quality of small grain cereal crops and is reflected in lower yields.
